7 Claims. (Cl. 235-613!) This invention relates to tabulating machinesand more particularly to machines of the type capable of sensingperforated records, interpreting the meaning of the perforations,controlling the operation of printing mechanism to print the amountsrepresented by the perforations on the records, and for controlling theentry of the amounts in the accumulator mechanism.

Machines of the above type have been utilized for printing on theperforated records to form checks issued for payment of some monetarytransaction. It is very desirable that the amounts be printed in thechecks at two places, one by protective type, that is, pin-point typecapable of resisting alterations, and also to print the amount by typewhich is more legible.

Machines of the above type have been found to be highly accurate intheir operations when used commercially. Nevertheless any singleinstance of improper printing should be guarded against, however rareits occurrence.

Such improper operations may result from wear of parts, dust, change inadjustment of parts, and the signaling to the user of such a change isan indication of a requirement of service for such machines to preventrepetition of improper printing.

It is, therefore, the main object of the present invention to provide amachine capable of printing two equal amounts by a single operation ofthe machine and to provide a comparing mechanism for indicating to theoperator if the amounts printed were not equal.

A still further object of the invention is to provide an accumulatorwith means to effect the entry of such amounts in the accumulator and toprovide means to prevent the entry of the amounts if the printed amountsare unequal.

More specifically it is an object of the present invention to analyze arecord, to provide means under control of the analyzing means to controlthe setting of two sets of type bars to print amounts at two places on arecord, to cause the entry of such amounts in an accumulator, to providemeans to compare the setting of the two sets of type bars, and means toprevent the printing and entry operations, whereby an amount will not beentered in the accumulator nor printed upon the record.

A still further object of the invention is to provide a read-outmechanism settable under control of the type bars for reading out theamounts represented by the already set type bars, and entering the samein the accumulator. Such an arrangement insures that the entered amountis always the same as the printed amount.

Other objects of the invention will be pointed out in the followingdescription and claims and illustrated in the accompanying drawings,which disclose, by way of example, the principle of the invention andthe best mode, which has been contemplated, of applying that principle.

Card feeding mechanism In more detail, l0 (Fig. 2) represents the maindrive shaft of the machine. This may be driven in any suitable manner asby an electric motor through belt Ii rotating a pulley attached to ashaft 15?. .A uni-directional coupling I2 is interconnected betweenshaft IO and I51.

From shaft in a worm I3 (Fig. 2) drives worm wheel l4 secured to a shaftii to which is also secured a box cam IS. A pivoted cam follower arm Hhas a roller l8 at one end riding in the cam groove and at the other hasconnection to an arm l9 through adjustable rod 20.

Arm I9 is secured to a shaft 2| having arms 22 (see Fig. 1) in pin andslot engagement with pickers 23 mounted for reciprocation in the frameof the machine. This reciprocating picker mechanism is adapted toadvance one record card at a time from the supply stack or magazine 24.

Shaft |51 through gears 25 shown in Fig. 2 drives a parallel shaft 25which has threaded sections 21 meshing with worm gears 25 on feed rollershafts 29 to drive feed rollers 35 (F18. 1) constantly. The card whichis advanced by the picker passes into the bite of the first pair of feedrollers 35 to the left in Fig. 1 and is subsequently guided to theanalyzing or perforation reading devices which comprise brushes 3! and acontact roller 32. These brushes and contact roller are of conventionalstructure such as is commonly used in electrically controlled tabulatingmachines.

,After passing the analyzing brushes 3|, the cards pass to the secondpair of feed rollers 30 which advance each card to a pair ofintermittently driven rollers comprising upper spring pressed rollers 33and lower rollers 34 which engages the edge of the card. These rollers33 and 34 advance the card to printing position at which time theymomentarily pause in their rotation to stop the feeding of the card topermit printing on the card in accordance with the preceding analysis.

This interruption in the advance of the card is accomplished as follows:Rollers 34 are secured to a shaft 35 (Fig. 1) journaled in the frame ofthe machine and having attached at one end a gear 35 (Fig. 2) meshingwith a gear 31 on shaft 35 on which shaft is also a gear 39 adapted tobe driven by a mutilated gear 49 free on the continually running shaftl5. Gear 40 carries a pin 40a (see Fig. 3) which may be set in any oneof five slots 49b in a disk 49c which is integral with worm wheel |4.Gear 40 is supported by a sleeve 49d which is loosely mounted on theshaft l5.

During the rotation of shaft ii the gear 40 will pick up gear 39 bymeans of the teeth thereof -to advance the card to printing position,upon reaching which, the toothless portion of gear 40 moves into lockingengagement with gear 39 as shown in Fig. 3. After printing has beeneffected gear 39 is again engaged for rotation and the card is fedforward to a conveying means (Fig. 1) comprising rollers 4| and tracks42 which convey the card to a suitable stacker 43 where they arecollected. The shafts upon which rollers n are secured are adapted to becontinually driven by reason of the gear connections 44 to the shaft 25as shown in Fig. 2. It is the frictional engagement of rollers 4| withthe upper surface of the card which causes the card to be advanced alongthe tracks 42.

It will be apparent that by altering the relationship between gear 45and wheel l4, the position on the card in which printing is effectedwill be altered. That is, if the gear 40 is so adjusted that the camportion is earlier effective in its time of operation, the card will besooner interrupted in its advance and a lower line will receive theprinting impression.

Printing mechanism For eflecting the printing on the record cards asthey successively pass through the machine a plurality of type bars 45(Fig.1) are provided. These bars are all mounted for reciprocation inthe frame of the machine and each have a connection through aspring-pressed pawl 45 to a. crosshead 41. Thus, in Fig. 1, uponmovement of crosshead 41 to the left the pawls 45 through frictionalengagement with bars 45 will move the bars concurrently in the samedirection.

The bars may be arrested at any point in their travel and subsequentlythe pawls 45 will disengage and permit the further movement of thecrosshead 41. Upon the reverse movement of crosshead 41 the shouldersI55 of the bars 45 will be engaged thereby to positively move the barsto restored position. For reciprocating crosshead 41 the followingmechanism is provided.

As shown in Fig. 2 the crosshead 41 is connected at its ends to blocksv45 slidable uponrods 49 and having pivoted link connections 59 to afollower arm 5| pivoted at 52. Arm 5| has a roller 53 cooperating withthe cam groove of a box cam 54' mounted on a shaft 55 connected throughworm gear 55 and worm 51 to the constantly running shaft ID. Thearrangement and timing of the parts is such that the type bars 45 areadvanced under the influence ofpawls 45 synchronously with the movementof a card past the analyzing or sensing brushes 3|.

If a perforation at, say, the 5 position on the card is under thesensing brushes, the corresponding type representing 5 will be at theprinting line. The establishment of an electric circuit through theindex point perforations by the brushes is adapted to energize a magnet53.

There are a number of these magnets 55, each magnet being related to acorresponding type bar 45. The energization of any unagnet is adapted torelease a pawl device 59 through a wire 5| and latch 52 and allow it toengage one of the ratchet teeth 59 on the bar 45. After pawl 59 hasengaged the teeth 55 further movement of the type bar 45 to the left inFig. 1 is prevented. The type bars 45 are positioned during a passage ofa card past the brushes. Subsequently these type bars are held duringthe period that a card passes from the analyzing station to printingposition and during the printing operation. After the printingoperation, pawls 59 and latches 52 are positively restored in thefollowing manner.

Secured to shaft 55 is a cam 53 (Fig. 1) against which presses theroller of an arm 54 and which latter is pressed upwardly by a spring 55acting through an arm 55 on shaft 51. The shaft 51 has secured theretoarms 55 which carry a restoring plate 59. Arms 19 pivoted on a rod 154:and having a pin and slot connection to arms 59 carry a restoring plate1|. By this construction cam 53 is adapted to move plate 59 to the leftto restore pawls 59 and plate 1| is moved upwardly to restore latches 52and their connected wires 5|.

For each type bar 45 there is an individual hammer 12 which is adaptedto strike the particulartype 13 on the type bar which is at the printingline. The hammers are pivotally mounted on a rod 14 carried by a bar 15and depend for their actuation upon movement of said bar. The bar 15 ispivoted on the frame of the machine by means of pintles co-axial withrod 14 and has springs 15 biasing the bar in a clockwise direction inFig. 1.

To the middle of bar 15 there is pivoted a cam follower arm 11bifurcated to straddle shaft 55 and having a roller 11a in cooperationwith a cam 19. Fixed to one face of the cam 15 is a cam member 19 whichcooperates with a projection of the cam follower arm 11.

As the cam 15 revolves, by virtue of the shaft 55 being driven in themanner previously described, it cooperates with the arm 11 through itsfollower roller IIa, gradually retracting the hammers 12 in acounterclockwise direction against the tension of springs II.

As the roller Ila leaves the high point of the cam 10, member I engagesthe projection 00 and upon continued rotation of the cam the pro-Jection 00 drops from the member I0 and the springs I0, thus released,turn the common bar I in a clockwise direction to swing the hammers I2against type 13 thus eifecting printing.

Referring to Fig. 1, 0i designates a printing platen Journalled in theframe of the machine and adapted to be turned by frictional engagementwith the passing card to prevent excessive wear at any one place. Theinking ribbon de- 01 vices are of conventional form and require nodetailed description the ribbon 02 being guided along the platen 0i andbeneath the tabulating card.

Circuit diagram (Fig.

In machines of this type it is desirable that the circuits which areclosed through the perforatio'ns in the card to magnets 50 beinterrupted before the brushes 3i leave the perforations in order toprevent arcing at the brushes. To this end circuit breaker contacts 08are provided as shown, in Fig. 10.

These contacts 08 are adapted to be closed by a dentated cam 09 rotatedby a shaft which is geared to the shaft 55 so as to rotate twice foreach rotation of shaft 55. Contacts 00 make contact just after theanalyzing brush 3i makes contact with the roller 32 and open suchcontact before the perforation has left the brush 3i. The circuit to themagnet 53 through the hole in the card is as follows:

From line 9i through circuit breaker contacts 88, card lever relaycontacts I25b closed when cards are being fed, wire 03, to commoncontact roll 32, brushes 3i, plug connections 95, magnets 58, switches98, wire 99, wire I00 to other side of line IOI.

A set of switches I02 as more particularly explained in Patent No.1,946,900 is provided and the switches 98 are opened and switches I02are closed to conduct the above described sensing circuit from magnets58 through switches I02, wire I03, cam contact. CC-I, wire 99, wire I00to line side IOI. 0am contact CC-i and other CC contacts are controlledby cams on the shaft 55 and cam contact CCI is timed to be opened duringthe time the 12th, 11th and 0" index points on the card arrive at thesensing brushes and to close just after the 0" index point has passedthe brushes so that the occurrence of a perforation in the 0," 11 or 12"positions will not be efiective to control magnet 58 in the columns inwhich switches 90 were opened and switches I02 closed.

In the present machine both switches 98 and I02 are closed as shown inFig. 11 so that contacts CC-I are ineffective. This will permit theperforations at the 11, 12 and 0" positions to control the position ofthe type bar to print related characters. However, for printing digitsrepresenting amounts printed on checks, 11 and 12 are not printed.However, under control of the 0 perforation, the zeros are printed, andas will be later evident, are checked for accuracy in printing.

Referring now to the circuit diagram (Fig. 10) certain of the mechanicalparts are shown in a diagrammatic manner in this view. In this figure Mis the driving motor which by the belt and pulley connection drives themain drive shaft II of the machine. This shaft through the gearingdescribed drives the picker devices, which ad-' vance the feed rolls tofeed the card past the cooperating brushes 3| and passing the brushesthe usual card lever is pressed by the cards thus closing card levercontacts 02.

To start the machine into operation the operator first closes main lineswitch I2I. Thereupon start key I22 is depressedvwhich upon the closureof its contacts establishes a circuit from line 0i, wire I20, throughstart key contacts I22, wire I23, motor relay magnet I24, motor M, wireI00, to other side of line "II. The energization of the motor causes thefeeding of cards to close the card lever contacts 92 and cause theenergization of card lever relay magnet I25 through a circuit from line9i, card lever contact 02, wire I26, magnet i25, wire I21, to the lineIII. This closes the relay contacts I25a which together with relaycontacts I2|a establishes a holding circuit for the motor M from theline 9i through stop key contacts I28, relay contacts I25a, relaycontacts I35a, (now closed) relay contacts I2la, motor relay magnet I24,motor M to line IN.

A cam contact CC-2 is provided to hold this circuit during the intervalbetween cards when relay contacts I25a will be open and the circuitfollows from line 9i, line I20, cam contacts CC--2, wire I30, relaycontacts I35a '(now closed),

relay contacts I24a, motor relay magnet I24,

through motor M to line I0i as before. Contact CC-2 also serves to takethe are from the relay contacts I25a with which it is in parallel.

Printing of zeros is effected by the usual zero suppression devices thedescription of which is not necessary for an understanding of thepresent invention but which may be of the form shown and described inthe patent to G. F. Daly, No. 1,946,900,1ssued February 13, 1934.

Multiple amount printing The card check illustrated in Fig. 7 shows theprinting of the amount 789.81 in protective type, that is, pin pointmaterial piercing type, under control of the printing control magnets50. For printing this data five printing bars are utilized. In sometypes of check writing work it is desirable to'print the same amount onthe check in another position and in more clearly readable type, asidentified by reference numeral I31 in Fig. 7.

To this end there is provided five supplemental type bars set in thesame manner previously described but are under control of five printercontrol magnets 58a (see Fig. 10). The magnets 58a are plug connected byplug connections I30 to the brushes 3i and therefore, receive impulsesat the same time to effect the printing of a corresponding amount on thecheck, as shown in Fig. 7.

Adding amounts printed on checks The machine is provided with anaccumulating mechanism for adding together the amounts represented bythe successive card checks and which amounts are printed on the cardchecks.

The accumulating mechanism is of a type well known in the art since itsconstruction is employed in tabulating machines of a commercial type andfor this reason is only generally described herein.

The setting of the type bars is utilized to control the entry of amountsin the accumulator and the entry part of the cycle occurs after thesetting up of the type bars, as will be shown in I normal and in anydifferential position of the type bar always makes contact with acontact making plate I and at a differential position of spring elementI40 makes contact with one of a series of wire bus bars I42, dependingupon the adjustment of the type bar 45. There are five spring contactmaking plates I4] and each has a wire connection to a relatedaccumulator control magnet I43 (see Fig. The nine bars I42 have wireconnections I430 to the nine contact points I44 of an emitter Em. Thecontact points I44 of the emitter Em are contacted by a rotatable brushI 45. The brush I45 of the emitter Em is driven by a shaft to be laterreferred to and which rotates twice for each machine cycle butv due tothe opening of the circuit to contacts 55, timed to close during thesecond rotation of cam 09 at the same time that the brush I45 closes thecircuits to the adding control magnets I43, card lever relay contactsI25b, a

. wire I45, contacts I41, closed after the type bars have been set, aswill be explained, relay contacts I350 normally closed, brush I45, acontact point I44, 9. related bar I42, contact spring I40, contact plateI, control magnet I43, and a wire I45 connected to one side of all thecontrol magnets I43 and to the line side IOI.

In Fig. 4 there will be seen the contacts I41 which are closed by a pinI40a carried by the cross head 41 in the extreme rocked position of thecrosshead, that is, after the type bars have been differentially set.The cross head remains in this position during the operation of theemitter Em. Contacts I41 are opened, of course, during the first closureof the circuit breaker contacts 50 to thus prevent adding operationsduring the type bar setting operations.

As previously intimated the accumulator is of a type well known in theart and is fully shown and described in the patent to C. D. Lake, No.1,307,740, dated June 24, 1919. The transfer mechanism for thisaccumulator is shown in the pgaiagntto Hollerith No. 974,272, dated Nov.1, 1

As shown in Fig. 8 the accumulator control magnets I43 correspond to themagnets desighated by numeral 1 in Patent No. 1,307,740 which controlthe operation of clutches to differentially set accumulator readingwheels I45, so that data entered therein may be visually read.

The drive shaft I 50 of the accumulator unit carries a gear I 5| meshingwith, a pinion I52 rotatable with a gear I53, the latter meshing with aPinion I54. The latter is rotatable with a gear I55 meshing with a gearI55 (Fig. 2)

attached to a shaft I51, and which shaft I51 Is constantly driven by thebelt II. By these gear connections the machine has driving connectionsto drive the accumulator drive shaft I50 provided for the accumulatorunit.

It is Pointed out that the shaft I50 drives the brush I45 of the emitterEm for reading out electrically the setting of the type bars 45.

Checking for simultaneous positioning of the twosets of time bars It isdesirable to check the position of the two sets of type bars toascertain whether the simultaneous positioning ofboth sets is effected.This is performedby mechanism shown particularly in Figs. 4 and 6 andexplained in connection with the wiring diagram.

For each type bar of the two sets there is provided a camming lever I50pivoted at I to the crosshead 41 and provided with a high portion I52cooperating with the tail I50 (Fig. 4) of the pawl 45 when the crosshead41 is moved slightly to the left, as will be made clearer later. Thecamming lever I50 is also provided with a-recess I5I to the left of thehigh portion I52.

When the pawl 52 is unlatched (as shown in Fig. 6) due to theenergization of the magnet 55 after a short travel of the type bar 45the pawl 59 will engage the notch 50 to stop the type bar 45 and as thecrosshead continues further after the type bar is stopped a cam edge I53of thestopped type bar 45 will rock the pawl 45 so that the tail I50 inengagement with the portion I52 of level I50 will rock the lever I50 sothat it actuates a T-shaped lever I54, the latter being carried by apair of arms II5 loosely mounted on rods I55. A continued rocking of thepawl 45 will cause the tail I50 thereof to slip by the high portion I52and into the recess I5I, permitting both the lever I50 and T-shapedlever I54 to be rocked upwardly to normal by a spring connected to eachlever I54.

For one denominational order of the type bars 45 the upper arm I55 hasintegral therewith an arm I51 adapted to close a pair of contacts I53a.Each of the five type bars of one set will cause the closure of arelated pair of five pairs of contacts I550.

For the next denominationally ordered type bar of the same set it willbe seen from Fig. 5

that the lower arm I55 has an integral arm I50 adapted to close its pairof contacts I55a. This construction is desirable in order to provide forthe proper side spacing of the five pairs of contacts I55a since each issubstantially wider than a type bar 45. The above arrangement isrepeated for the next two adjacent orders of the same set of type bars,as best shown in Fig. 5.

A, similar construction is provided for the other set of type bars andthe five pairs of controlling contacts are designated I55b in Fig. 10.

Obviously for the same denominational order the contacts I55a and I55bclosed by type bars 45 of two sets will close at the same time if bothtype bars are set to the same positions to thus cause the energizationof relay magnets I15 and HI (Fig. 10) controlled by contacts I554: andI55b, respectively, by a circuit now to be described with reference toFig. 10.

This circuit is from line side 0i, a wire I12 leading to a wire I13connecting one side of all the contacts I5Ba and I551), through eithercontacts to the related magnet I10 or "I, to a wire I14 connecting oneside of all the magnets I10 and HI, and a wire I15 to line side IOI.

The relay magnet I'll when energized closes relay contacts l'llb (Fig.10) and opens relay contacts Illa, while the energization of relaymagnet I'II closes relay contacts I'Ilb and opens relay contacts Illa.Wires I'll and"! are connected to the blades of relay contacts "Oh andIllb and relay contacts I'Ilaand "la in such a manner that if both relaymagnets I18 and I'll are energized simultaneously a circuit betweenwires I'll and I18 will be kept open, but if either magnet III or Ill isenergized at a time dissimultaneous with the energization of the othermagnet the circuit between wires I18 and I18 will be closed to cause theenergization of the relay magnet I35. This circuit is from the line side8|, a wire I88 to cam contacts CC-A, wire "8 to wire I13 and generallyspeaking through certain relay contacts which are shifted to closedposition from open position while the other relay contacts remainclosed, circuit breaker contacts I8I, relay magnet I35, and wire I82 toline side I8I. Circuit breaker contacts I8I are'closed by a dentated camdriven by the same shaft as cam 88, prevlously referred to.- Camcontacts (JO-4 are opened during the second closure of contacts I8Ihence these contacts are ineffective as shown by dotted timing points inFig. 11 for contacts I8 I.

Attention is directed to the timing diagram in Fig. 11 wherein it willbe seen that the contacts I8I, I88a, I58b are timed to close A of apoint later than the contacts 88 this lag being due to the fact that ittakes a short time to close contacts I880 and I882; after the type barsare stopped in their travel. From Fig. 6 it will be appreciated that fora particular index point circuit breaker contacts 88 first close tocause the closure of the circuit to the magnet 58 to cause the stoppageof the type bar. After the energization of magnet 58 the type bartravels slightly until it is stopped. After the type bar is stopped thecrosshead continues further in its travel to the left and a slightinterval in time occurs before the related contacts I68a or i581: areclosed.

Taking the case now for a particular denominational order, say theunits, and considering the corresponding setting of the units type barsof the two sets it will be seen that if the card is perforated at the "3index point position, for example, that contact points 88 close to causethe simultaneous energization of control magnets 58 and 58a. At threequarters of a point in the cycle later the contact points I58a and I 58band circuit breaker contacts I8I close simultaneously to cause theconcurrent energization of magnets I78 and I'll. Thus magnet I18 opensits contacts H811 and closes its contacts I18!) and magnet I'll opensits contacts "Ia and closes its contacts "lb and at the same timecircuit breaker. contacts I8I close and cam contacts CC4 are closed thuskeeping the circuit to magnet I 35 open.

However, if the type bar for one set should inadvertently be stopped atthe 2 position, for example, its contacts I58a, will be closed to causethe energization of relay magnet I18 before relay magnet I'll isenergized at the 3 index point position. At the time circuit breakercontacts I8I close at the 2 point (Fig. 11), relay magnet I18 will closeits contacts IIIlb thus completing a circuit from theline side 8|, wireB88, cam contacts (JG-4 now closed, relay contacts I'I8b, to relaycontacts i! la now closed, wire I119, circuit breaker contacts I8I nowclosed, relay magnet I35, wire I82 to the line side I8I.

Relay magnet I35 will now close relay contacts I355 to provide a stickcircuit through cam contacts 00-5 to the line side 8i.

The energization of relay magnet I35 will open its relay contacts I3lathus opening the circuit to the motor M. The hammers II are adapted tobe released .for striking the selected type 13 at the time in the cyclesubstantially at the time disclosed in Fig. 11, this occurring after allthe type bars have been set. In practice it has been found that theenergization of the relay magnet [35 will cause the storm-8e of themotor M prior to the time that the hammers are released to preventimproper pririting upon the perforated card.

The indication given by the stoppage of the machine with cards in themagazine 24 informs the operator that an improper printing operation hasbeen prevented. With the machine stopped after partially completing itscycle of operation, the operator inserts a rod I83 (Fig. 1) in themachine frames to block the hammers 12 and prevent them from strikingthe type I3. The

1 machine is provided with a hand wheel I88 (Fig.

8) and by manually turning this the shafts I51 and I8 (Fig. 2) areturned so as to complete the cycle of machine operation to feed the cardpast the hammers 12. when the card has reached such a position the rodI83 can be removed and the machine restarted so as to complete printingoperations on the remaining cards. The unprinted card can, of course, belocated in the storage hopper or if the operator watches carefully itcan be received by hand as it is fed by the last set of rollers 4|.

Obviously, since relay contacts I350 (Fig. 10) are opened the circuit tothe adding control magnets I43 is opened during the time the machine isoperated by the turning of the wheel I 84. Cam contacts CC--5 are closedduring the remainder of the cycle to retain relay magnet I35 energizedand thus relay contacts I35c are retained closed to prevent entry in theaccumulator of the amount represented by the unprinted perforated card.

The type bars are restored at the end of the cycle of machine operationas previously stated by causing the cross bar I! to contact withshoulders I85 of the type bars 45 restoring the latter to their homeposition, as shown in Fig. 1. As the crosshead returns to home positiona plate I88 contacts with the extremity of the levers I58 causing themto be rocked to disengage the tail I68 from the recess I6I, as bestshown in Fig. 1. At the initial operation of the machine the crossheadcarries the lever I58 out of engagement with the cam plate I permittingthe lever I58 to be rocked so that the tail I68 occupies a position ontop of the portion I 52 of the lever I58 as shown in Fig. 4, the partsnow being in position to cause the closure of contacts IBM or I58b bythe stoppage of the type bar, as previously explained.

Resetting of accumulator the motor M to operate.

Cam contacts CC-3 close a circuit from the line side 9 I, by wire I 28,the other reset key contacts Isl, cam contacts 00-3, to a reset clutchmagnet I02, and to the line side IM to cause the energization of thereset clutch magnet I02.

Bhaft I has secured thereto a gear I00 (Fig. 8) adapted to drive a gearI04 through an idler gear I00. The gear I04 has attached thereto aclutch disk I00 (Fig. 9) both the clutch disk and gear being looselymounted on a shaft Il'l. Attached to the shaft Ill-is an arm I00carrying a clutch pawl I00 and to said shaft there is secured a gear 200meshing with a gear 2" attached to the reset shaft 202 of theaccumulator.

Obviously, the clutch disk continually rotates and the cam .contacts-CC-l are timed to close the circuit to the reset clutch magnet I02 atsuch time that the clutch notch 20! of the clutch disk is registeredwith the clutch tooth 204 of the clutch pawl I". The energization of thereset clutch magnet I02 attracts its armature 200 to release the clutchpawl I to cause the clutch engagement to drive the reset shaft 202. Themanner of resetting is very well known in the art and for more completedetails of construction and operation reference may be had to the patentto C. D. Lake, No. 1,600,414.

General summary of operation In order that the operation of the machineas a whole may be better understood, a brief rsum of its operation willnow be given.

The operation of the machine is initiated by the depression of the Startkey which closes ..its contacts I 22, referring to Fig. 11, which willeffect the energization of the motor control relay I24 and also closethe circuit of the motor M. The operation of the motor M will cause thedrive shaft II to be rotated and cam I0 will thereupon be rotated torock shaft 2| (Fig. 2). The rocking of the shaft 2i, referring to Fig.1, will reciprocate the card picker 20 to thereby advance a card fromthe magazine 24 to the first set of feeding rollers 80 (Fig. 1). As thecard emerges from the first set of feeding rollers 30, it will bedisposed between a contact roller I2 and the analyzing brushes ii andthe card perforations will be analyzed as the card is fed past thebrushes 3|. During the analysis of the card perforations, the crosshead41 will be shifted to cause the movement of the type bars 45synchronously with the analysis of the perforations. when the analyzingbrush encounters a perforation, the related type bar 4! is stopped inits movement to thereby cause, for a plurality of type bars, their digitrepresenting settings in order to bring type 13 representing such digitsto the printing line. The setting of each of the type bars 40 iseffected by the energization of a printing control magnet at adifl'erential time. After the type bars have been set to represent thedigits corresponding to the perforations analyzed, they remain indiflerential adjusted position and during this time, the card is beingfed from ,the analyzing .brushes Si by the second set of feeding rollers30 to convey the card between rollers 03 and 34 and the latter feed thecard so that the leading marginal edge of the card is cooperativelyrelated with a platen 0|. When this relationship is obtained, therollers 03 and 04 are stopped in their rotation, thereby retaining thecard in cooperation with the platen II. The hammers I2 (Fig. 1) are nowreleased to eflect the printing from the selected type II. Thereafterthe rotation of rollers 00 and 04 is resumed, causing the feeding of thecard further to the right, as viewed in Fig. 2, away from the platen 0|so that by a series of rollers 4|, the

printed card may be directly fed to the storage receptacle--40. The typebars are, nevertheless. retained in their differential adjusted positionin order that a read-out device carried thereby may eil'ect the entryinto an accumulator of the amount printed on the card.

The electrical circuits for effecting the energization of the type barcontrol magnets 00 are shown in Fig. 10 and referring to the wiringdiagram, the circuit extends from the line side 0| through impulsedistributor contacts 00, relay contacts I201: now closed, to the contactroller 02. Upon the-presence of a perforation, contact is made betweenan analyzing brush II and the contact roller 32, thereby effecting theenergization of a related magnet 50, the circuits for the magnets 50being closed through cam contact c-l which from Fig. 11, it will beseen, is closed during the time that the perforations are analyzed. 1

By plug connections I30, the analyzing brushes 3| are adapted to effectthe energization of a supplemental set of magnets 50a to cause thesetting of a second set of type bars. sets of type bars 45 controlled bythe sets of magnets 50 and 50a are adapted to effect multiple printingon the card, as shown in Fig. 7.

In order to effect the entry of the amounts represented by the card, oneset of type bars 45 is provided with contact making elements I40 whichare differentially positioned to make contact with digit representingbars I 42 (Fig. 10), the elements I40 and bars I42 providing an amountread-out device. The'type bars remain in their diiferentially adjustedposition during approximately the second half of the operating cycle, asis shown in the timing diagram in Fig. 1l,and with the contact elementsI40 in their differentially adjustedposition, an emitter Em will readout the digit settings of the contact elements I40 during the secondhalf of the operating cycle to eflect the energization of accumulatorcontrol magnets I43 (see Fig. 8) at difl'erential times, thereby causingthe entry of an amount in the accumulator.

After the accumulator entry operation and during the final part of theoperating cycle, the crosshead 41 (Fig. l) is returned to its normalposition, thereby restoring both sets of type bars to their normalpositions.

The present machine also includes a checking device whereby thepositions .of the two sets of type bars are compared and the amount isentered in the accumulator in accordance with the result of thecomparing operation. The electrical comparing means includes two sets ofcontacts, contacts I080 being closed by one set of type bars andcontacts "50b being closed by the other set of type bars. Referring toFig. 10, upon the simultaneous closure of contacts I60a and I00b foreach denominational order, related magnets I10 and III will beenergized. Referring to the top oi Fig. 10 each of the last mentionedmagnets will effect the closure of the related contacts I 10b and "lband at the same time, when the type bars are differentially stopped atthe same position in each denominational order. Upon the setting of thetwo sets of type bars in corresponding positions for all of thedenominational orders, magnet I35 will remain deenergized. In the eventthat in a particular denominational order the type bars are not set tothe same digit The two checking device is operated during the first halfof the operating cycle, during which. time the two sets of type bars areset to digit representing positions and in the event that one of thetype bars of one set is improperly adjusted, the relay magnet I" will beenergized to cause the opening of contacts "to (Fig. This will open thecircuit to the emitter Em and even though the latter operates during thesecond half of the operating cycle, the accumulator entry operation willnot be effected.

In order that the operator will know of the improper operation, it ispreferable upon this detection to cause the machine to stop in itsoperation. In the present machine this is preferably effected by theopening of contacts "to which, as shown in Fig. 10, open the stickcircuit of the motor control relay I24 and the motor M. The latter willstop in its operation and in practice the motor will be stopped prior tothe time that the hammers are'released in order to prevent the improperprinting upon the perforated card.

After a series of cards has been printed and the amounts are entered inthe accumulator, the latter may be reset by the depression of a resetkey I90. This will cause an operation of. the motor M and at the sametime effect the energization of the reset clutch magnet I92 and thelatter will cause the resetting of the accumulator in a manner which iswell known in the art and which is fully shown and described in thepatent to C. D. Lake, No. 1,600,414.
